Display last three entries in a table

I want to show just the last three entries from a mysql database.

I have the code to show the full table but could do with some help to tweak it to show just the last 3 entries from the table.

Can anyone help me out?

It's probably pretty easy for you php guys

//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password) 
  or die("Unable to connect to MySQL");


//select a database to work with
$selected = mysql_select_db("#####",$dbhandle) 
  or die("Could not select examples");

//execute the SQL query and return records
$result = mysql_query("SELECT * FROM readersubmit ORDER BY id DESC");



//fetch tha data from the database 
while ($row = mysql_fetch_array($result)) {

   echo "<p>".$row['submit']. "</p>"; //display the results
   
}
//close the connection
mysql_close($dbhandle);

PHP:

 

Just Replace
//execute the SQL query and return records
$result = mysql_query("SELECT * FROM readersubmit ORDER BY id DESC");

with
//execute the SQL query and return records
$result = mysql_query("SELECT * FROM readersubmit ORDER BY id DESC LIMIT 0,3");

 

Thanks very much muslim_ansari that worked a treat.
